Maternal COVID-19 in pregnancy linked to 29% higher risk of child neurodevelopmental issues, study finds.
A 2025 study of over 18,000 births in Massachusetts links maternal COVID-19 infection during pregnancy to a 29% increased risk of neurodevelopmental disorders in children by age three, including autism, speech delays, and motor issues.
The research, published in Obstetrics & Gynecology, found that 16.3% of children exposed to the virus in utero received such diagnoses, compared to 9.7% of unexposed children, with higher risks when infection occurred in the third trimester and among males.
While the study identifies an association, not causation, and does not establish biological mechanisms, researchers emphasize the importance of protecting pregnant individuals through vaccination and infection prevention.
